Troubleshooting Email Errors

ERROR listmailuser: '/tmp/docker-mailserver/postfix-accounts.cf' does not exist

Dovecot is not started until the first email account is created, therefor listing email accounts with the command opencli email-setup email list before creating any email accounts, will produce error:

root@stefi:/usr/local/mail/openmail# opencli email-setup email list
2024-08-27 07:55:15+00:00 ERROR listmailuser: '/tmp/docker-mailserver/postfix-accounts.cf' does not exist
2024-08-27 07:55:15+00:00 ERROR listmailuser: Aborting

Solution: Create an email account first with opencli email-setup email add.

Error: auth-master: userdb lookup(user@example.net): connect(/run/dovecot/auth-userdb) failed: No such file or directory

Immediately after creating first email account, dovecot is still creating necessary files in the background, so running the opencli email-setup email list immediately after creating first email account will produce an error:

root@stefi:/usr/local/mail/openmail# opencli email-setup email list
doveadm(stefan@stefi.openpanel.site)<577><>: Error: auth-master: userdb lookup(stefan@stefi.openpanel.site): connect(/run/dovecot/auth-userdb) failed: No such file or directory
